However, outside her core base of support, all this electability has a dark side with Clinton. She has extraordinary negatives. She galvanises the conservative movement in ways no other Democrat can. Against McCain, she and she alone enables the Republicans to forget their deep internal divisions and unite. Nothing – nothing – unites them as she does. The money she will raise for the Republicans is close to the amount they can raise for themselves. If you’re a hard-nosed Democrat, especially in a state that leans Republican or that voted for Bush, she is potentially toxic to your chances. No Democrat in Nebraska wants to counter an advertisement morphing his face with Hillary’s.
